android从资源文件中读取文件流并显示的方法

private void doRaw(){
  InputStream is = this.getResources().openRawResource(R.raw.ziliao);
  try{
    doRead(is);
  }catch(IOException e){
    e.printStackTrace();
  }
}
private void doRead(InputStream is) throws IOException{
  DataInputStream dis = new DataInputStream(is);
  byte[]buffer = new byte[is.available()];
  dis.readFully(buffer); 
  textView.setText(new String(buffer));
  dis.close();
  is.close();
}
//就是用this.getResources().openRawResource这个就可以了
